This invention relates to engines.

One of the objects thereof is to provide` e, simple and reliable engine of the internal .combustion t it v H .y `and in condition for eficient'action.

in which the cylinders,

valves and ot er parts are maintained cool l other object is to provide an engine of l the above type in which any tendency of the piston to bind or become otherwise ineH- l 20 f i cientl is 'done away with.

oOt/her objects will be in part obvious and in art pointed out hereinafter.

^ vhe invention accordingly consists in the features of construction, combinations of elements and arrangement ol' parts which will be exemplified in' the construction herein-I l after set forth, and the scope o' the application of which will be following claims.

In the accompanying drawings, wherein is shown one of Various pdssible embodiments of my invention, Figure 1 is a side elevation thereof, certain parts being broken away upon lines a-a and b-b of Fig. 2, in order to show the construction more clearly; Fig. 2 isa sectional plan, the,sec tiOnal portions thereof being taken substantially on the lines c---cv and d-rl of Fig. l; Fig. 8 isa sectional plan of a cylinder-head on a somewhat larger scale than lfig. 2; Fig. 4 isa sectional elevation taken substani tially on the line e-c of Fig. 3.

Slmilar reference characters refer to similar' artsthroughout the several views of the rawings.

In order to 'render certain features of this invention more readily and fully understood, it may here be noted that in interna] combustion engines a largo amount of heat is necessarily generated in the cylinder or cylinders with a corresponding tendency to high temperatures of/thecylinder walls and adjacent parts. Such temperatures are highly undesirable, not only'on account ol their tendency to draw the temper of the indicated in the I have also found in the metal, to war the same and to cause undue cxpansion'anc binding of the parts, but by reason of the extreme difficulty 0f lubrication, the lubricant being, in some instances, burned out almost as rapidly las applied. running of internal combustion engines that under the heat; conditions obtaining in general practice there is a tendency for the pistonto expand Within the cylinder walls andbind therein, with .i consequent cutting of the I of power. The above and ot er defects are avoided in constructions of the nature 0f that hereinafter described.

Referring now to the accompanying drawings, there is shown a which a plurality of cylinders 2 are formed in a single piece. This casting, which is provided with projecting portions to adapt it to be securely mounted upon the engine bed, is yformed with grooves 3 and 4 extending entirely about the same, as best shown in Fig. l of the drawings. Within these grooves are penned the upper and lower edges of a metallic sheet 5, preferably of copper. This sheet is inwardly inclined at its lower portion, as at 6, and, as the portion of casting edge of the sheet rests extends outwardly from the cylinder walls, the sheet is spaced from these Vwalls and forms a jacket space 8.

Detachablymounted upon the casting 1 are the cylinder heads 9 of which, as the same are substantially identical, one only will be described lin detail. Head 9 is provided with inlet and outlet valves 10 and l1, to which passages 12 and 13 lead respectively from the carburetor and to the exhaust. These valves control ports leading downwardly into the cylinder, as at 14, being operated by a vertical movement of their stems 15. The details of this valve mechanism form in themselves no part of the present invention and are not claimed herecylinder casting 1 in 'in inasmuch as they, in common with certain other features, are shown, described and claimed in my (x0-pending application Serial No. 378,574. filed June 12, 1907. The walls 1G surrounding the valvcs10 and 11 and walls 17 forming a third valve-chamber 18 outline a space or passage 19 through which the jacket water is adapted to pass. This jacket water space 19 is ,in general above the level of the lower wall 20 in which the several valveseats and the spa1k-p1ugs arts and loss v 7 in which the upper therethrough and ed in said heads,

water passage leadingfrom the lower portion of one side thereof to the upper portion of another side4 thereof, and means connecting said jacketing means about said cylinder withsaid passage in said head, said head being detachably mounted upon said cylinder and said connecting means beingl separable,4 W A 6.'In apparatus of the class described, in combination, a plurality of c ,linders cast integral one Wit another, `jaclieting means about said cylinders, a lurality of heads mounted upon 4said cylin ers, valves mountsaid cylinders being provided with Walls inc-losing said valves and with means adapted to guide jacketl Water over the outer surface of said Walls, and connections leading from said jacketing means about said cylinders to said passages in said heads.
